Rheumatoid Arthritis Symptoms: Early Signs, Stiffness and Flares

01Basics

What autoimmune inflammatory arthritis means

Mayo Clinic describes rheumatoid arthritis as a chronic condition that causes pain, swelling and inflammation in the joints, and can also damage other parts of the body, including the skin, eyes, lungs, heart and blood vessels. It is an autoimmune condition: the immune system attacks the body’s own tissues by mistake.

It differs from the more common osteoarthritis, which Mayo Clinic links to wear on the joints from use. Rheumatoid arthritis affects the lining of the joints (the synovial membrane), which becomes inflamed and thickened, and can wear away the bone beneath. Over time this can make joints bend out of shape. Some people have both conditions.

02Early signs

Early symptoms in the hands and feet

Both sources say the small joints of the hands and feet are often the first to be affected. Mayo Clinic notes it may affect just a few joints at first, and that as it progresses it can spread to the wrists, elbows, hips, knees and ankles.

The NHS explains that symptoms often develop gradually over several weeks, but some cases progress quickly over a few days. It says the condition typically affects joints symmetrically, on both sides at the same time and to the same extent, but that this is not always the case. Symmetry is common, not a requirement for the diagnosis.

03Joint symptoms

Pain, swelling and warmth

The NHS describes the joint pain as usually throbbing and aching, often worse in the morning and after inactivity. The joint lining becomes inflamed, so joints can swell and become hot and tender to touch. Mayo Clinic lists painful, warm, swollen joints among the main symptoms.

Some people develop rheumatoid nodules, firm swellings under the skin around affected joints or over pressure points such as the elbows. Our guide on joint effusion explains swelling inside joints more generally.

04Stiffness

Morning stiffness and stiffness after rest

Stiffness is a key symptom. The NHS says affected joints can feel stiff, for example making it hard to bend the fingers fully or make a fist, and that stiffness is often worse in the morning or after a period of inactivity.

The NHS notes that morning stiffness in osteoarthritis usually wears off within 30 minutes of getting up, while in rheumatoid arthritis it often lasts longer. Mayo Clinic says it can last 45 minutes or longer. These are typical patterns, not strict cut-offs: how long stiffness lasts cannot confirm or rule out the diagnosis by itself.

05General symptoms

Fatigue and symptoms beyond the joints

Both sources describe general symptoms: tiredness and lack of energy, fever or a high temperature, sweating, poor appetite and weight loss.

Inflammation can also affect other parts of the body. The NHS mentions dry eyes and chest pain if the heart or lungs are affected. Mayo Clinic lists possible effects on the skin, eyes, lungs, heart, nerves and blood, and complications such as osteoporosis, dry eyes and mouth, more infections, carpal tunnel syndrome, heart and lung problems and a higher risk of lymphoma.

06Flares

Flares, remission and variation

Both sources stress that symptoms vary from person to person and can come and go or change over time. Mayo Clinic explains that flares, periods when the condition is more active, follow periods of less or no swelling and pain, called remission. The NHS describes flares as times when the condition deteriorates and symptoms get worse.

Mayo Clinic notes that smoking seems to make the condition worse in people who keep smoking. The sources do not describe a fixed sequence of stages that everyone passes through; the course differs between people and is influenced by treatment.

07Diagnosis

Similar conditions and uncertainty

Joint pain and stiffness have many causes, including osteoarthritis and other inflammatory conditions. Symptoms alone cannot confirm rheumatoid arthritis; a doctor’s assessment is needed.

Mayo Clinic says the cause is not known, but it is likely a mix of genes and environmental factors, possibly with hormones and certain viral infections. Risk factors include being female, middle age, a family history of rheumatoid arthritis or other autoimmune conditions, smoking, serious gum disease and excess weight. Having risk factors does not mean you have the condition.

08Seeing a doctor

Getting prompt medical assessment

Mayo Clinic advises making an appointment if you have ongoing pain and swelling in your joints that is not getting better after several weeks. If symptoms are severe, spreading or affecting your daily life, there is no need to wait that long before asking for an assessment.

Before the appointment, it helps to note which joints are affected and whether on one or both sides, how long morning stiffness lasts, any swelling or warmth, general symptoms such as tiredness or fever, how symptoms affect tasks such as gripping, dressing or walking, and any family history of autoimmune conditions.

09Sources

Where the sources differ

Duration of stiffness. Mayo Clinic says morning stiffness can last 45 minutes or longer; the NHS contrasts it with osteoarthritis stiffness that usually settles within 30 minutes. Neither figure is a diagnostic rule.

Symmetry. Mayo Clinic says symptoms most often affect the same joints on both sides; the NHS adds explicitly that this is not always the case.

Currency. The NHS page was last reviewed in March 2023 and its planned review date has passed; Mayo Clinic’s page is from April 2025. Both sources here focus on symptoms rather than treatment; Mayo Clinic notes that newer medicines have greatly improved treatment options.

10Summary

In summary

Rheumatoid arthritis is an autoimmune condition that inflames the lining of the joints. Early signs often appear in the small joints of the hands and feet, usually on both sides: throbbing pain, swelling, warmth and stiffness that is worse in the morning or after rest. Tiredness, fever, sweating and poor appetite can also occur, and symptoms come and go in flares.

Symptoms alone cannot confirm the diagnosis, and the course varies between people. Ongoing joint pain and swelling deserves prompt assessment by a doctor, who can arrange tests and treatment. Keeping a short record of affected joints, stiffness and daily limitations helps that appointment.
